First of all, I had forgotten I made the rear storage compartment removable. Here you can see it removed. (You can also see how I made the cupola able to rotate.) You can also see the two antennae that attach to the compartment. I had planned on making them removable, using magnets, but the magnets didn't hold firmly enough. Notice the brass pins, which give the needed security. (Why removable, why not just glue them on? Two reasons, 1) Glued-on is begging to be broken off. 2) There is a location on the casement for an antenna, but its kit didn't come with one.)
Let's start with the casement. I drilled out the hinge, and inserted a pin, allowing it to open. I installed a magnet and drilled a hole to accept the antenna. This cupola is smaller, so the 'turret' commander will not fit. I had to remove most of this one's base to fit. I glued a disk with a magnet in the bottom of the cupola.
I guess there is going to be a Pt.2.5
